Abstract
The technique of simultaneous estimation of frequency and DOA is addressed. Based on signal subspace rotation and sampling of array signal and its delayed version, a new method is presented for the simultaneous estimation of frequency and DOA of multiple signal sources. By forming a so-called signal space matrix, the estimated parameters of frequencies and DO As are paired automatically. Simulation results show that the proposed method is effective.
